Abstract (en)
[origin: US2019089242A1] A power supply device according to the present invention detects a value of an input voltage (power supply voltage) by an input side voltage detection circuit, and decreases a comparative voltage (error voltage) that is compared with an on timer signal (timer signal) for determining an on time of a switching element based on the value of the input voltage. The power supply device employs an on-time control and at the same time reduces the total harmonic distortion.
